Pacific is a very buggy place in Defcon. Bombers attack out of range without doing damage, which just gives away your position. Ships sometimes take dumb routes moving near Indonesia and Australia, wasting time and even unintentionally using land bugs. Silo nukes do not fly the way the preview suggests, ruining your launch. Bombers can nuke with extra range, messing up your nuke dodging.

(Random side note: all of those bugs are fixed in Minicom)

It is a very unique place to fight. In some ways fighting there is completely different than fighting in other parts of the world. Also, my friend Arstotzka loves it. So yes, it is a nice idea.
